Thanks for posting this up (this is the Rom out of my car).
I have done a bit of work on it today, can't really say I got that far, but starting with the info posted by GTODesign
here I at least got the fuel and Ign maps and axis right, or hopefully they are.
Attached is the little bit of xml file for the above tables.
Other Maps I have found, but not identified yet are
3E6D 19x19
441A 3x12
450A 6x10 (same map also at 4566)
46A9 7x10
47DB 10x10?
489D 10x10
4A0A 16?x14
While the ecu appeared to have the id 98650014, it appears to actually be 98640014.
Any further input/tips most welcome
Cam
